      A good fit if…

      • You want a certified 2-ton central heat pump at a typical efficiency level.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.
      • You mainly need heat - its HSPF2 is below average for central heat pumps.
      • You want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions5
      What is the SEER2 rating of the WeatherMaker PH7TAN424**AA?
      The WeatherMaker PH7TAN424**AA is rated at up to 17.0 SEER2 and 12.5 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the WeatherMaker PH7TAN424**AA good for cold climates?
      It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 2-ton model.
      How much does the WeatherMaker PH7TAN424**AA cost to run per year?
      At its rated efficiency it costs about $682-$1,959 a year in electricity in large U.S. cities, depending on climate and local rates - for example $860 in Phoenix and $1,651 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Which indoor units work with the WeatherMaker PH7TAN424**AA?
      ENERGY STAR lists 3 certified combinations for this outdoor unit. The highest-rated one uses EVM4X31M17A.
      What refrigerant does the WeatherMaker PH7TAN424**AA use?
      It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

      Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
